CS-AP裸眼砾石充填防砂浅析

Analysis of CS-AP Open-hole Gravel Pack

裸眼水平井能穿越较长的油层,井筒与储层具有最大的接触面积,能最大限度的开采油藏等,但是对于某些稠油油藏,由于原油流动性差以及地层出砂严重,使得油层和优质筛管之间不能形成很好的砂桥,需要用一种适合油藏特性的防砂方式进行开发。

The open-hole horizontal wells is suitable for the long reservoir,and maximize to exploit the oil through the maximum interface between the wellbore and reservoir. But for the heavy oil reservoirs,they can’t form a good sand bridge between the reservoir and screen pipes due to the poor liquidity and sand flowing seriously. Therefore,we have to research and introduce a new method to resolve the problems.
